A matriz energética dos países da América Latina e Caribe tem um dos maiores índices de energias renováveis, quando comparada à de outras regiões do mundo. No entanto, até 2009, cerca de três quartos de sua estrutura correspondia a combustí

Zwitterionic, cationic, and anionic per- and polyfluoroalkyl substances (PFASs) are identified in aqueous film-forming foam (AFFF) concentrates and AFFF-impacted sites. However, the mobility potential of zwitterionic and cationic PFASs is poorly unde

Nowadays, Brain-Computer Interface (BCI) systems are considered a tool with enormous potential to establish communication alternatives, restore functions, and provide rehabilitation processes to patients with neuromotor impairment. A wide variety of

The derailment of an unmanned train carrying crude oil and subsequent fire in the town of Lac-Mégantic, Quebec, led to the use of 33 000 L of aqueous film forming foam (AFFF) concentrate. While it is known that per- and polyfluoroalkyl substances (P

Sites impacted by the use of aqueous film-forming foams (AFFFs) present elevated concentrations of perfluoroalkyl and polyfluoroalkyl substances (PFAS). The characterization of the PFAS contamination at such sites may be greatly complicated by the pr

The aerobic biotransformation over 180 days of two cationic quaternary ammonium compounds (QACs) with perfluoroalkyl chains was determined in soil microcosms, and biotransformation pathways were proposed. This is the first time that polyfluoroalkyl c

The total oxidizable precursor (TOP) assay can be useful for integrating precursors to perfluoroalkyl acids (pre-PFAAs) into the assessment of sites contaminated by per- and polyfluoroalkyl substances (PFAS). Current research gaps include risks of in

As an important reservoir of pollutants, soil may play a critical role in altering isomer ratios of perfluorooctane sulfonate (PFOS) or PFOS precursors (PrePFOS) via microbial processes, but this possibility has not yet been investigated, as well as

The comprehensive analysis of aqueous film forming foam (AFFF) formulations has led in recent years to the discovery of novel classes of perfluoroalkyl and polyfluoroalkyl substances (PFASs). Whether the pre-existing analytical methods for historical
